我为 caffe 编写了 python 层，它可以读取 hdf5 并满足我的一些操作需求。但是在 python 设置方法中打开和读取 hdf5 文件时我遇到了一些问题。这里是。当我在设置中使用带有代码的表格时：

def setup(self, bottom, top):
    h5file = tables.open_file("/home/titan/models/hdf5/train_small.h5", driver="H5FD_CORE")

运行网络时出现此错误：

Traceback (most recent call last):
  File "/home/titan/scripts/python_layers/pydata_hdf5.py", line 37, in setup
    h5file = tables.open_file("/home/titan/models/hdf5/train_small.h5", driver="H5FD_CORE")
  File "/home/titan/anaconda/lib/python2.7/site-packages/tables/file.py", line 318, in open_file
    return File(filename, mode, title, root_uep, filters, **kwargs)
  File "/home/titan/anaconda/lib/python2.7/site-packages/tables/file.py", line 784, in __init__
    self._g_new(filename, mode, **params)
  File "tables/hdf5extension.pyx", line 465, in tables.hdf5extension.File._g_new (tables/hdf5extension.c:4872)
tables.exceptions.HDF5ExtError: HDF5 error back trace

  File "../../../src/H5FDcore.c", line 273, in H5Pset_fapl_core

  File "../../../src/H5Pint.c", line 3371, in H5P_object_verify
    property list is not a member of the class
  File "../../../src/H5Pint.c", line 3321, in H5P_isa_class
    not a property list

End of HDF5 error back trace

当我使用 h5py

def setup(self, bottom, top):
    self.data = h5py.File('/home/titan/models/hdf5_nose_mouth/train_small.h5', 'r')

我有同样的错误：

Traceback (most recent call last):
  File "/home/titan/scripts/python_layers/pydata_hdf5.py", line 11, in <module>
    import h5py
  File "/home/titan/anaconda/lib/python2.7/site-packages/h5py/__init__.py", line 31, in <module>

ValueError: Not a property list class (Not a property list class)

当我使用 deepdish 时：

def setup(self, bottom, top):
    self.data = dd.io.load('/home/titan/models/hdf5/train_smallest.h5')

我也有错误：

Traceback (most recent call last):
  File "/home/titan/scripts/python_layers/pydata_hdf5.py", line 36, in setup
    self.data = dd.io.load('/home/titan/models/hdf5/train_smallest.h5')
  File "/home/titan/anaconda/lib/python2.7/site-packages/deepdish/io/hdf5io.py", line 476, in load
    with tables.open_file(path, mode='r') as h5file:
  File "/home/titan/anaconda/lib/python2.7/site-packages/tables/file.py", line 318, in open_file
    return File(filename, mode, title, root_uep, filters, **kwargs)
  File "/home/titan/anaconda/lib/python2.7/site-packages/tables/file.py", line 784, in __init__
    self._g_new(filename, mode, **params)
  File "tables/hdf5extension.pyx", line 488, in tables.hdf5extension.File._g_new (tables/hdf5extension.c:5081)
tables.exceptions.HDF5ExtError: HDF5 error back trace

  File "../../../src/H5F.c", line 1582, in H5Fopen
    not file access property list
  File "../../../src/H5Pint.c", line 3321, in H5P_isa_class
    not a property list

End of HDF5 error back trace

但是当我只阅读 *.txt 文件时，一切正常。我也可以从控制台读取这个文件并在 caffe 的 hdf5 层中使用它。请帮助我，我如何从 python 层读取 hdf5 文件？

尝试安装另一个版本的 h5py。我刚刚解决了它：

pip install h5py==prev_version

我想这与链接有关，但知道哪个是导致此问题的确切原因会很有趣。
